UNITED STATES* PATENT oei-lon HUGH W. HARRIS, 0F ATLANTA, GEORGIA, ASSIGNOR TO UNDERWOOD TYPEWRITER COMPANY, OF NEW YORK, N. Y., .A CORPORATION OF DELAWARE,

TYPEYVRITING MACHINE.

Application filed October 12, 1920.

To all fzohmn. it may concern:

Be it known that l. lilUon ll". lrlunns, a citizen oii" the lll'nited States, residing in Atlanta, in the county ot Fulton and State ot' Georgia, have invented certain new and useful Improvements in rlypeivrltir chines, oi? which the followingr is n cation.

The present invention relates to type ing machines havingr sets ot feed-rolls arranged one 'forward of the other in linespaee direction relatively to the platen, so that a pliuality of super-posed Work-sheets with interlezived carbonesheets may be `gripped und ied between the feed-rolls and the platen, and in which the Work-sheets may comprise as a iirst or top sheet a narrow statement-sheet, and as a second sheet a wider ledger-sheet projecting at its opposite margins beyond the statement-sheet, and as a third sheet a prooisheet underlying the ledger-sheet and which maybe Wider and project at its opposite margins beyond the ledger-sheet. More particularly,` the present invention relates to means for rela-tively positioningT or collatingl the several Worksheets after these Work-sheets have been inserted around the platen between the platen and the feed-rolls.

The preesent invention is a` further development ot' the paper-feeding mechanism disclosed in my Patent No. ltleifl, ot February 18, 1919; and also ot the typewriting machine forming,r the subject of my pending' application for patent, serial No. 32 3,304. tiled October Q5, 1919. Also my present invention is herein disclosed as embodied in a typewriting machine in which the mech-- anism for supportingy and castingv off the feed-rolls is generally similar to that disclosed in the patent to Helmond, No. 1,058,672, ot April 8, 1913.

The broad idea involved in the present invention, and also in my above-noted prior inventions, relates to means `for holding certain selected wirk-sheets stationary, While other worksheets are ted relatively thereto either forward or baclnvard by rotatingr the platen; for example, holdingr a. statementsheet stationary while an underlying- Wider ledger-sheet is adjusted relatively to the statement-sheet, and also holdingr both the statement-sheet and ledger-sheet stationary While a proofsheet nearer the platen is adjusted relatively to the. statement-sheet and Serial No. 415,3?1.

leflgeissl.V vit, whereby relative adjustment ot al. three sheets may be effected. In the conf-truction disclosed. in my above-noted Patent No. 1,291,156, this result is accomplished by means ot mechanism for selectively lockingfeed-rolls' -which are in Contact with the AWork-slieets which are to be held stationary. .in the constriu'ition disclosed in my abovenoted application serial he. 33 ,301, a simq ilar result is accomplished by means ot mechanism for selectively casting off feed rolls from the Worin-:accts which are to be held stationary While other Work-sheets on the platen are adjusted relatively thereto, rictional holding devices being pressed against the Worksheets which are to be held stationary.

According to the present invention as herein disclosed, front and rear feed-rolls are offset. relatively to each other in the direction ot the length ot the platen, so that one of these feed-rolls will engage the narrow top sheet While the other of' these rolls Will engage the projecting margin of a Wider underlying sheet, so that. by casting oil' the teed-roll trom the narrower top sheet the Wider underlying sheet may be ted forward r backward by the platen relatively to the top sheet, and by casting' oft both leed-rolls another underlying sheet nearer to the platen may be adjusted relatively to the two outer sheets. More particularly, according to the present invent-ion as herein disclosed, a rear complete or continuous set of axiallyaligned feed-rolls has its inner rolls engageable with the narrower outer or top sheet, its outer rolls being engageable with the laterally projecting margins ot an underlying' Wider sheet; and a iront set of axiallyaligned teed,-i'olls has the feed-rolls thereof axially spaced so as to engage only the laterally projecting margins oi the wider underlying sheet, leaving` the narrower top sheet tree to pass opposite the open space between these spaced forward Yfeed-rolls. In this construction, when both sets ot eedafolls are in engagement, all the supcrposed Worksheets and their interleaved carbons may be red in line-space direction by rotating the platen. By casting of? the rear set of feedrolls, the aXilfilly-spaeed feed-rolls of the toi-'ward setvsill cooperate with the platen to ifecd the Wider underlying Work-sheets, While lezwing` the narrower top Worksheet stationarv By casting; oit both sets of feedlio rolls, both the narrower top sheet and the wider underlying sheet may remain stationary while another underlying' sheet nearer the platen may be moved with the platen in line-space direction.

For assuring effective operation in. the manner above noted in adjusting the several superposed work-sheets, normallv ineffective trictional holding' devices are provided and are actuated to the engaging position concomitantly with the casting off ot the feed-rolls, thereby to hold stationaryY the work-sheets from which the feed-rolls have been cast oti,

@ther features and advantages will hereinafter appear.

In the accompanying draivings',

F igure l is a front. view, showingmv invention embodied in a platen trame ot the type employed in the Underwood typewriting machine, with the several parts in normal position tor l'zvpine, and in which all oi the superposed work-sheets mayv be 'ted in line-spacing direction.

After this, the second finger-piece et may be deiliressed to the linal position thereo't'. shown in Figure 5, therebj,7 casting oit also the forward 'Feed-rolls l) and concomitantlv moving the outer set ol t'riction-men'ibers 3S into engagenient with the margins ot the ledgersheet il. vln this ,tinal disposition ot' the movable parts, both sets of leed-rolls are in the cast-otliposition and both sets of 'triction-members are in the engaging position. Bv rotating` the platen l, the prooi-sheet C may non' he collated or adjusted relativelv to the previously-collated ledger-sheet P) and statement-sheet Br, so that when this last ci'illating operation is completed the three work-sheeisl A. ll and C ivill be in correct collated relation. y now pushing toi-Ward the lirst finger-piece B5, this finger-piece will tarrv with it the second linger-piece 41h, and all o if the parts will be returned to the original normal or typing position thereoil. shown in Figures fl, Q and 3, and Writing upon the collated sheets may proceed. The top or statement-sheet n, ma)7 he adjusted to the correct position for Writing either beifore or after the several sheets have been collated as above described. To accomplish this result` the first Enger-piece 35 may be moved troni the initial position thereof, shown in Figure 3, to the final position thereot', shown in l"igure o, Without operating the second linger-piece 418? which, thereforey Will he left in its initial position. appearing in Figure 3. thereby fasting otl'l all of the feed-rolls while still leaving all of the friction-members in the disengaged position, whcufeln7 all ot the work-sheets ma;T he moved with. the platen`r both for originali)T insertine' the work-sheets and for brinoiiw i 2' h b the top sheet A into the correct position 'tor type-writing thereon. The lirst fingerpiece 35 will be retained in this depressed position with all ott the feed-rolls in the cast-oli position` by reason ot the shape oli the operating` cams Q8 on the operating shait QT, as will be clear trom an .inspection of Figure Variations may be resorted to within the scope ot the invention, and portions et the improven'ients may be used Without others.
